Poincaré's Lemma -- from Wolfram MathWorl

  1. Poincaré's Lemma. Poincaré's lemma says that on a contractible manifold, all closed forms are exact. While implies that all exact forms are closed, it is not always true that all closed forms are exact. The Poincaré lemma is used to show that closed forms represent cohomology classes

  4. The Poincaré lemma. We first define the form versions of cycles and boundaries in homology: In this context, the term Poincaré lemma can refer to either the property exact ⇒ closed ( d 2 = 0), or the converse statement closed ⇒ exact under certain topological conditions, which we address next
  5. Poincaré lemma. The Poincaré lemma states that if B is an open ball in R n, any smooth closed p-form ω defined on B is exact, for any integer p with 1 ≤ p ≤ n. Translating if necessary, it can be assumed that the ball B has centre 0. Let α s be the flow on R n defined by α s x = e −s x
  6. Poincar´e Lemma January 6, 2009 There are several proofs of the Poincar´e lemma. This note is an exposition of a proof that appears in [1]. It is more than a proof. It is an algorithm for finding a form µ so that ω = dµ when dω = 0 on a rectangular parallelopiped in Rn. We need a little information about differential forms. This discussion is brief, but should be enough to define.
  7. Lemma in the setting where the role of functions is played by formal power series. Introduction. The formal Poincar´e Lemma is what comes out when one tries a power series approach to proving the usual Poincar´e Lemma (which, it will be recalled, says that a closed form is locally exact). The key to the constructions we give is the realisation that the usual exterior derivative can be.

Das ist nicht so wichtig. Wichtiger ist noch, dass h - und damit auch f - nicht diffbar sein muss. Also wäre das Poincaré-Lemma auch für sternförmige Gebiete nicht anwendbar, solange h jedenfalls nicht diffbar ist. Aber wenn wir mal annehmen, h sei diffbar, und das Poincaré-Lemma testen, stoßen wir auf ein positives Ergebnis. Das ist doch mal ein Anhaltspunkt. Jetzt nehmen wir uns irgendeinen Punkt, der nicht der Nullvektor ist, und legen eine Halbgerade von diesem aus durch den.

In mathematics, the Poincaré metric, named after Henri Poincaré, is the metric tensor describing a two-dimensional surface of constant negative curvature.It is the natural metric commonly used in a variety of calculations in hyperbolic geometry or Riemann surfaces.. There are three equivalent representations commonly used in two-dimensional hyperbolic geometry

Das Poincaré-Lemma besagt, dass jede auf einer sternförmigen offenen Menge \({\displaystyle U\subseteq \mathbb {R} ^{d}}\) definierte geschlossene Differentialform exakt ist. Die Aussage lässt sich abstrakter auch so formulieren: Für eine sternförmige offene Menge \({\displaystyle U\subseteq \mathbb {R} ^{d}}\) verschwindet die \({\displaystyle k}\)-te De-Rham-Kohomologie für alle \({\displaystyle k>0}\) As a mathematician and physicist, he made many original fundamental contributions to pure and applied mathematics, mathematical physics, and celestial mechanics. In his research on the three-body problem, Poincaré became the first person to discover a chaotic deterministic system which laid the foundations of modern chaos theory. He is also considered to be one of the founders of the field of topology. Poincaré made clear the importance of paying attention to the invariance of laws of.

This paper proves a discrete analogue of the Poincaré lemma in the context of a discrete exterior calculus based on simplicial cochains. The proof requires the construction of a generalized cone operator, p: C k (K) → C k + 1 (K), as the geometric cone of a simplex cannot, in general, be interpreted as a chain in the simplicial complex.The corresponding cocone operator H: C k (K) → C k.

It is our hope that a Poincaré lemma can become in the sub-Riemannian context as powerful and influential as its elliptical, classical, version Our first result is the classical Poincaré lemma. Its proof is elementary and does not use the Hodge-Morrey decomposition. Its drawback (compare with Theorem 8.3) is that it does not provide the expected gain in regularity and is restricted to contractible sets However, every point of the rigid analytic space in the classical sense (with residue field finite over the base field) has a fundamental system of étale neighborhoods given by polydiscs, on which the Poincaré lemma is true, so that one may show that the de Rham complex is locally exact at these classical points for the Berkovich étale topology. This is discussed in details in Berkovich's. the discrete Poincaré lemma. The generalized cone operator is a combinatorial operator that can be constructed for any simplicial complex that can be grown by a process of local augmentation. In particular, regular triangulations and tetrahedralizations of R2 and R3 are presented, for which the discrete Poincaré lemma is globally valid. 2004 IMACS. Published by Elsevier B.V.

The Poincaré-Bendixson theorem is a classical result in the study of (continuous) dynamical systems. Colloquially, it restricts the possible behaviors of planar dynamical systems: such systems cannot be chaotic.
